In 2 denotes reference numeral 31 the drive motor as an electrically operated machine. For example, the drive motor has gate 31 a non-illustrated rotor mounted to drive a shaft of an electric automobile, etc., and rotatably disposed, and a stator disposed outwardly of this rotor in the diametrical direction. The above rotor has a rotor core, and permanent magnets arranged at an equal distance in many positions in the circumferential direction of the rotor core, and a magnetic pole pair is constructed by the S pole and the N pole of the permanent magnet. The above stator has a stator core in which teeth are formed so as to protrude inward in the diametrical direction in many positions in the circumferential direction. The stator also has stator coils 11 to 13 as coils of U-phase, V-phase and W-phase wound around the above teeth.

In the output shaft of the above rotor is a magnetic pole position sensor 21 is arranged as a magnetic pole position detecting section for detecting a magnetic pole position of the rotor. This magnetic pole position sensor 21 generates a magnetic pole position signal SGΘ as a sensor output, and sends this magnetic pole position signal SGΘ to a drive motor control device 45 as a control device of an electrically operated machine. In this embodiment mode, a resolver becomes the magnetic pole position sensor 21 used.

An electrical DC from a battery 14 is converted into an electric phase current, ie, electric currents Iu, Iv, Iw of the U phase, the V phase, and the W phase by an inverter 40 is converted as an electric power generator to the electric automobile by driving the above drive motor 31 to operate. The electric currents Iu, Iv, Iw of the respective phases are respectively the stator coils 11 to 13 fed.

Therefore, the above inverter has 40 Transistors Tr1 to Tr6 as six switching elements, and sends a drive signal generated in a drive circuit 51 to each of the transistors Tr1 to Tr6.

A voltage sensor 15 as a voltage detection section is in the access side in supplying the electric power from the above battery 14 to the inverter 40 arranged. This voltage sensor 15 detects a DC voltage Vdc of the access side of the inverter 40 , and sends this DC voltage Vdc to the drive motor control device 45 , As the DC voltage Vdc, a battery voltage can also be used. In this case, a battery voltage sensor is in the above battery 14 arranged as a voltage detection section.

The electrically driven drive unit is by the above drive motor 31 , the inverter 40 , the drive circuit 51 , an unrepresented drive wheel, etc. built. reference numeral 17 denotes a capacitor.

An unillustrated recording apparatus such as RAM, ROM, etc., for recording data and various types of programs is in the drive motor control apparatus 45 in addition to a non-illustrated CPU that functions as a computer. First and second electric current command value maps are set to this recording device. Instead of a CPU, an MPU can be used.

Various kinds of programs, data, etc. are recorded to the above ROM, but may be recorded on another recording medium such as a hard disk, etc. arranged as an external spoke In this case, for example, is a flash memory in the above drive motor control device 45 and the above programs, data, etc. are read from the above recording medium and recorded to the flash memory. Accordingly, the above programs, data, etc. can be updated by exchanging the external recording medium.

Next, the operation of the above drive motor control device will be described 45 explained.

First, an unillustrated position detection processing means guides the above drive motor control apparatus 45 Position detection processing and reads the magnetic pole position signal SGΘ, which from the above magnetic pole position sensor 21 is sent, and detects the magnetic pole position 0 on the basis of this magnetic pole position signal SGΘ. Further, a rotation speed calculation processing means of the above position detection processing means performs speed calculation processing and calculates the angular velocity ω of the drive motor 31 in the above magnetic pole position signal SGΘ. The above speed calculation processing means also calculates a drive motor rotational speed NM as the rotational speed of the drive motor 31 NM = 60 * (2 / p) · ω / 2π on the basis of the above angular velocity ω, when the number of magnetic poles is set to p. A rotational speed of an electrically driven machine is established by this drive motor rotational speed NM.

An unillustrated detection electric current acquisition processing means of the above drive motor control apparatus 45 performs detection electric current acquisition processing, and reads and receives the above detection electric currents iu, iv. The detection electric current acquisition processing means obtains a detection electric current iw iw = -iu - iv by calculating this detection electric current iw on the basis of the above detection electric currents iu, iv.

Therefore, an unillustrated vehicle speed detection processing means guides the above drive motor control apparatus 45 Vehicle speed detection processing, and detects a vehicle speed V corresponding to the drive motor rotational speed NM on the basis of the above drive motor rotational speed NM, and transmits the detected vehicle speed V to an unillustrated vehicle control device for controlling the entire operation of an electric automobile. A command value calculation processing means for a vehicle in the vehicle control apparatus executes command value calculation processing for a vehicle, and reads the above vehicle speed V and an accelerator opening α and calculates a vehicle request torque TO * based on the vehicle speed V and the accelerator opening α. The command value calculation processing means for a vehicle further generates a drive motor target torque TM * corresponding to this vehicle request torque TO *, and sends this drive motor target torque TM * to the above drive motor control device 45 ,

In the propulsion engine control device 45 The above drive motor control processing means has an electric current command value calculation section 46 as an electric current command value calculation processing means, a weak field control processing section 47 as a weak-field control processing means, a voltage command value calculation processing section 48 as a voltage command value calculation processing means, a three-phase / two-phase conversion section 49 as a first phase conversion processing means and a PWM generator 50 as an output signal generation processing means, to the drive motor 31 on the basis of the drive motor target torque TM *.

The above electric current command value calculating section 46 has a d-axis electric current command value calculating section 53 and a subtractor 55 as a first electric current command value calculating processing means, and a q-axis electric current command value calculating section 54 as a second electric current command value calculation processing means to perform electric current command value calculation processing. The above d-axis electric current command value calculating section 53 and the subtractor 55 perform first electric current command value calculation processing, and calculate a d-axis sen electric current command value id * as a first electric current command value showing a target value of a d-axis electric current id. The q-axis electric current command value calculating section 54 performs a second electric current command value calculation processing, and calculates a q-axis electric current command value iq * as a second electric current command value showing a target value of a q-axis electric current iq. A maximum torque control processing means is set by the above d-axis electric current command value calculating section 53 and an electric current command value adjustment processing means is constructed by the above subtractor 55 built up.

The weak-field control processing section 47 has a subtractor 58 as a voltage saturation calculation value calculation processing means, and an integrator 59 as a voltage saturation judgment processing means and a vote value calculation processing means. The weak-field control processing section 47 performs low-field control processing, and automatically performs the weak field control when a battery voltage is reduced and the drive motor rotational speed NM is raised.

The above voltage command value calculation processing section 48 has an electric current control section 61 as an electric current control processing means and a voltage control section 62 as a voltage control processing means to perform voltage command value calculation processing. On the basis of the above d-axis electric current command value id * and the q-axis electric current command value iq *, the electric current control section performs 61 Electric current control processing, and calculates a d-axis voltage command value vd * and a q-axis voltage command value vq * as first and second axis voltage command values. The voltage control section 62 performs voltage control processing, and calculates voltage command values vu *, vv *, vw * as first through third voltage command values. The voltage command values are established by the above d-axis voltage command value vd *, the q-axis voltage command value vq *, and the voltage command values vu *, vv *, vw *.

In this embodiment mode, the above drive motor control device performs 45 A feedback control using a vector control arithmetic operation in a dq-axis model, wherein the d-axis is set to the direction of a magnetic pole pair in the rotor and the q-axis is set to the direction perpendicular to the d-axis.

The above electric current command value calculating section 46 performs electric current command value calculation processing, and reads the drive motor target torque TM *, the angular velocity ω and the DC voltage Vdc, and calculates the d-axis electric current command value id * and the q-axis electric current command value iq * Show target values of the d-axis electric current id and the q-axis electric current iq.

When the drive motor target torque TM * from the above command value calculation processing means for a vehicle to the drive motor control device 45 is sent, therefore, results in a torque command value limiting section 22 as a torque command value limit processing means of the drive motor control device 45 Torque command value limit processing and reads the above DC voltage Vdc, the angular velocity ω and the drive motor target torque TM *. With respect to the maximum drive motor target torque map of 3 , which is set in the above recording apparatus, reads the torque command value limiting section 22 Also, a maximum drive motor target torque TMmax * showing a maximum value of the drive motor target torque TM * corresponding to the above DC voltage Vdc and the angular velocity ω. The torque command value limiting section 22 further limits the drive motor target torque TM * so as not to exceed the maximum drive motor target torque TMmax *. A maximum target torque map of an electrically driven machine is constructed by the above maximum drive motor target torque map, and the maximum target torque of an electrically driven machine is constructed by the above maximum drive motor target torque TMmax *.

If the angular velocity ω predetermined value ω1 or smaller in the above drive motor target torque map is, the maximum drive motor target torque TMmax * has a constant Value. When the angular velocity ω exceeds the predetermined value ω1, in contrast, the maximum drive motor target torque TMmax * reduced in a curve shape. In an area where the angular velocity ω is the predetermined one Exceeds value ω1, the maximum drive motor target torque TMmax * is set big too be while the DC voltage Vdc is raised, and is also set small to be while the DC voltage Vdc is lowered.

Subsequently, the above d-axis electric current command value calculating section performs 53 Maximum torque control processing, and receives the drive motor target torque TM *, which in the above torque command value Begren Zung section 22 is limited. With reference to the first electric current command value map of 4 , which is set to the above recording apparatus, reads the d-axis electric current command value calculating section 53 the d-axis electric current command value id * corresponding to the drive motor target torque TM *, and sends this d-axis electric current command value id * to the subtracter 55 ,

In this case is in the first electric current command value map the d-axis electric current command value id * is set such that the absolute value of an electric current amplitude command value is minimized is to reach the drive motor target torque TM *. In the The above first electric current command value map has the drive motor target torque TM * a positive value, but the d-axis electric current command value id * has a negative value. When the drive motor target torque TM * Is zero (0), the d-axis electric current command value id * becomes Zero set. While the drive motor target torque TM * is increased becomes the d-axis electric current command value id * set to grow in the negative direction.

In the above drive motor 31 a counterelectromotive force is generated while the rotor is rotated. While the drive motor rotational speed NM is raised, however, the terminal voltage of the drive motor becomes 31 raised. When this terminal voltage exceeds a threshold, voltage saturation is generated and output using the drive motor 31 will be deactivated.

Therefore, an unillustrated voltage saturation judgment index calculation processing means performs the above voltage control section 62 Stress Saturation Evaluation Index Calculation Processing, and calculates a Stress Saturation Evaluation Index m m = √ (vd * 2 + vq * 2 ) / Vdc as a value indicative of a degree of voltage saturation, on the basis of the above d-axis voltage command value vd * and the q-axis voltage command value vq *, and sends the voltage saturation judgment index m to the subtractor 58 ,

The subtractor 58 performs voltage saturation calculation value calculation processing, and subtracts a constant k (0.78 in this embodiment mode) from the above voltage saturation judgment index m when a threshold value representing a maximum output voltage of the inverter 40 shows, to a comparison value Vmax is set Vmax = k · Vdc.

The subtractor 58 further calculates a voltage saturation calculation value ΔV ΔV = m - k and sends this voltage saturation calculation value ΔV to the integrator 59 ,

Subsequently, the integrator performs 59 Voltage saturation judgment processing and tuning value calculation processing, and integrates the above voltage saturation calculation value ΔV every control timing, and calculates an integration value ΣΔV. If this integration value ΣΔV has a positive value, the integrator multiplies 59 the integration value ΣΔV with a proportional constant and calculates a tuning value Δid for performing the weak field control, and sets this tuning value Δid to a positive value. When the voltage saturation calculation value ΔV or the integration value ΣΔV has a value of zero or less, the integrator sets 59 the above tuning value Δid to zero.

The subtractor 55 performs electric current command value adjustment processing, and receives the adjustment value .DELTA.id and tunes the d-axis electric current command value id * by subtracting the adjustment value .DELTA.id from the above d-axis electric current command value id *. The subtractor 55 then sends the tuned d-axis electric current command value id * to the q-axis electric current command value calculating section 54 and the electric current control section 61 ,

If the voting value Δid has a value of zero, in this case becomes substantially no d-axis electric current command value id * tuned and no weak field control is performed. If the voting value Δid has a positive value, in contrast, the d-axis electric current command value id * tuned and is raised in the negative direction, and the weak field control is performed.

Thus, when the d-axis electric current command value id * is calculated, the above q-axis electric current command value calculating section reads 54 the drive motor target torque TM * included in the above torque command value limiting section 22 is limited, and the d-axis electric current command value id *. With reference to the second electric current command value mapping of 5 , which is set to the above recording apparatus, calculates the q-axis electric current command value calculating section 54 the q-axis electric current command value iq * corresponding to the drive motor target torque TM * and the d-axis electric current command value id *, and sends this q-axis electric current command value iq * to the above electric current control section 61 ,

In the above second electric current command value map becomes the d-axis electric current command value id * set to be increased in the negative direction, and the q-axis electric current command value iq * is set to be raised in the positive direction, while the drive motor target torque TM * is increased. While the drive motor target torque TM * is reduced, the d-axis electric current command value id * set to become small in the negative direction, and the q-axis electric current command value iq * is set, in the positive To become small. When the drive motor target torque TM * is constant and the d-axis electric current command value id * in the negative direction increases Further, the q-axis electric current command value iq * in the positive direction small.

When the above tuning value Δid is zero and no weak field control is performed, and the value of the d-axis electric current command value id * that is to the subtractor 55 is sent, ida * is, such as in 5 is shown, according to the d-axis electric current command value id * to the q-axis electric current command value calculating section 54 as the value ida * sent as it is because the voting value Δid is zero. In the q-axis electric current command value calculating section 54 becomes the value of the q-axis electric current command value iq * iqa *. In contrast, when the tuning value .DELTA.id has a positive value and the weak field control is performed, for example, when the value of the d-axis electric current command value id * that goes to the subtractor 55 is sent ida *, the d-axis electric current command value id * becomes a value idb * large by the tuning value .DELTA.id in the negative direction in the subtractor 55 and becomes the q-axis electric current command value calculating section 54 Posted. In the q-axis electric current command value calculating section 54 For example, the q-axis electric current command value iq * is set to be small in the positive direction from the value iqa *, and becomes a value iqb *.

The above three-phase / two-phase conversion section 49 performs three-phase / two-phase conversion as a first phase conversion processing, and reads the magnetic pole position 0, and converts each of the detection electric currents iu, iv, iw into the d-axis electric current id and the q-axis electric current iq.
